Thanks for the pics, from what I can see you use the control arm hole as centering and its top edge as the vertical contact surface. Are the 3 screws for tightening the perch to the arm with the black washer from underneath? (I just want to eliminate any possible clunking if it's not tightened, stock springs clunk if rubber is removed from the bottom coil)
Any input on existing spring diameters and heights commonly available to test different spring rates? I guess I will use my FK perch at top and fit a machined perch for the same I.D. at the bottom. That KW bottom perch is 3 parts right? Male threaded top part with hexagonal hole accessible from underneath, female threaded bottom part and washer to tighten the part from underneath? Am I right on this?
